Karla Cheatham Mosley was born and raised in Westchester, New York. She graduated from New York University's Tisch School of the Arts with honors, and went on to study in France at the Roy Hart Vocal Institute. At a young age, Mosley performed in Sugar Beats, a children's rock group. In 2003, while still in college, Mosley joined the American counterpart of the Australian children's TV show Hi-5 (2003), where she became the youngest member of the group. After leaving the show in 2006, Mosley tried her luck on stage in various theatre plays as well the musical "Dreamgirls" across the US and off-Broadway in New York City. Minor TV and movie roles were followed by her first series regular part on the long-running soap-opera The Guiding Light (1952) where she played Christina Moore Boudreau from 2008 until the show's cancellation in 2009. Afterwards, Mosley and her co-star Lawrence Saint-Victor created the web series "Wed Locked" where they also starred in. This wasn't their last collaboration after all because in 2013 Mosley and Saint-Victor joined the daytime drama The Bold and the Beautiful (1987). Initially also intended as lovers on this show - and spinning-off a limited-run web-series called "Room 8" which they again wrote and starred in - Mosley's character of Maya Avant soon shot to front burner status. The first step was a romance with Jacob Young's Rick Forrester but eventually a highly publicized twist that the character of Maya is transgender really put her on the map. From 2013 to 2015 the actress also had a recurring role in prime-time television on Hart of Dixie (2011). In her private life, Mosley has been married to lawyer and civil rights advocate Jeremiah Frei-Pearson since 2011. She sits on the board of Covenant House, a privately funded agency providing shelter and other services to homeless, runaway and throwaway youth. She is also a celebrity ambassador for the National Eating Disorders Association and active in other charities.
